摘要： A user can specify rules governing access to location information for a portable device. The rules can impose time, date and location restrictions as well as impose restrictions regarding the type of location information that can be disclosed. The rules for the portable device are stored in association with a unique portable device identifier. Multiple devices owned by the same user can have separate sets of rules or identical rules. A uniform application program interface is provided to permit a third party to request location information. When a request is received, the rules database is accessed to determine whether the request can proceed and what limitations are imposed on the location information. The allowed location information is returned to the third party requester. The system allows the user to allow all or block all location information and provides an override mechanism to allow location information in the event of an emergency call.

摘要： A distributed radio system is disclosed. Transmit and receive packets of data are transported over a relatively high-speed multiplexed network, which in one embodiment may be an Ethernet network. The distributed radio system comprises in one embodiment a centrally-located network-level processing unit connected via network connections to one or more intermediate-level processing units. The intermediate-level processing units may be distributed throughout the coverage area. The processing units perform digital signal processing, as well as higher level processing such as signal routing, speech transcoding and proper interfacing to external environments, such as a macrocellular environment. Radio elements are provided that are accurately timed or synchronized, such that the radio elements have their own time base to ensure proper transmission, even when unpredictable network delays occur.

摘要： A system and method for delivering coupon messages to a consumer wireless device utilizes a fixed communication device that functions as a base station for the consumer wireless device. The fixed communication device has limited coverage zone. When the consumer wireless device comes within the coverage zone of the fixed communication device, the consumer wireless device selects the fixed communication device as the preferred base station. Upon completion of registration, the fixed communication device transmits one or more coupon messages to the consumer wireless device. The consumer may enter the associated retail establishment and complete a transaction using the received coupon message. The consumer wireless device may be viewed manually, or the display scanned or read electronically to accept the coupon message in the retail establishment.

摘要： A system for robust transmission in an orthogonal frequency division multiplexed (OFDM) communication network is disclosed. An individual wireless communication device is assigned a set of OFDM tones for transmission in an uplink timeslot. If the received signal is not satisfactory, the number of OFDM tones assigned to the individual wireless communication device may be doubled such that the OFDM signal is duplicated in the additional set of OFDM tones. This process can be extended to multiple additional sets of OFDM tones. The multiple sets of OFDM tones may be combined at the base station to enhance recovery of the original transmitted signal. The assigned OFDM tones need not be contiguous within a block of available tones. Because a large number of OFDM tones are available, the concept may be extended to a large number of duplicate sets of OFDM tones. In a Group Call operation, each wireless communication device in the call group may be assigned multiple sets of OFDM tones to provide for more robust transmission.

摘要： A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

摘要： A transaction authentication system uses a mobile unit to connect with a wireless network and with an authentication station using a short-range transceiver. Prior to a transaction, the mobile unit transmits an Identity to an authentication processor using the wireless provider network and receives a Hash and Identifiers therefrom. During a transaction, the mobile unit connects to an authentication station using a short-range air link and transmits its Hash. The authentication station transmits the received Hash to the authentication processor, which confirms the Identity of the mobile unit. If identified, the authentication processor sends a Private Identifier to the authentication station and the mobile unit connects using an air link with the Private Identifier. The authentication station sends a success message if it connects to the mobile unit using the Private Identifier air link. A device authentication message is sent to a transaction processor to process the requested transaction.

摘要： A system to permit push-to-talk communications in an orthogonal frequency division multiplexed (OFDM) communication network. Individual wireless communication devices that are part of a Group Call are assigned the same set or sets of OFDM tones for a downlink timeslot. Because each wireless communication device receives the same set of tones, each device will receive a communication simultaneously. The assigned OFDM tones need not be contiguous within a block of available tones. Because a large number of OFDM tones are available, the concept may be extended to a large number of groups that each separately support a Group Call function.

摘要： The identity of a mobile communication device can be authenticated to allow the device to access a web site without the need for a user log-in operation. The mobile device stores an identity token and sends it to the web server in the web browser data stream. Additionally, the mobile device transmits an identity token to an authentication entity using a data stream other than the web browser data. The authentication entity queries the wireless network to verify authentication of the mobile device. The identity token may be the mobile telephone number itself, a temporary mobile subscriber identity assigned by the mobile network, or encrypted or hashed versions of either. Alternatively, a new temporary mobile subscriber identity may be sent to the mobile device and retransmitted back to the authentication entity.
